**  So are you :

1.  Building a scanner ?

2.  Adding a new channel frequency to an ancient scanner that switches xtals
?

3.  You have one you need to replace or have no idea what it should look
like ?

4.  The xtal is really a crystal filter  ??

5.  Do you have the slightest idea how to specify a crystal in order to get
one made ??


 So many possibilities  -  such a non-communicative poster ......

 And it top posts too.

 Sigh .........

**  Errr,   152.475  x  3  +  10.7  =   468.125  MHz.

That frequency is Channel 12  -  used by the  NSW Police "special
operations" and the QLD Police for Wynnum (now digitally encrypted ).

What make and model scanner? It's extremely unlikely that the crystal
frequency is that high.

**  My bet is that our "klo" is trying to modify a UHF CB rig to receive and
transmit on the police band.

      Very criminal.

Try contacting Hy-Q www.hy-q.com.au with the make and model scanner and
frequency you wish to receive.  Usually they can provide details on crystal
type and cost.
